This Lex is fully loaded (DTS,DD,THX EX)with version 4 software. The upgrade was performed at the Lexicon factory just over 6 months ago and a complete diagnostic test was performed and the unit is functioning flawlessly. There are no scratches or problems of any sort on the unit. I have the original box, manuals and both remotes. Any questions or offers to purchase please email me directly. I can also email pictures. $1120 OBO plus shipping. This is back on the market. The deal I had fell through. Sorry for the inconvenience.
